Be it known that I, SAMUEL T. Cntr, a citizen of the United States, residing at Lit tleton, in the county of Arapahoe and State of Colorado, have invented certain new and useful improvements in Automobile-T ire Pumps; and l ldo declare the following` to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to malte and use the saine.

iiy invention hasfor its principal object to provide an extremely simple and inexpensive, yet a highly etlicient and durable pump for infiating' automobile tires, the device beinp; so constructed that it may be easily attached and detached to an automobilel inV such a manner as to be driven by one of the rear whe-els of the latter when such wheel is suitably raised above the ground.

further ob`ect is to so construct the de vice as to permit a common form of automobile pump to he used in uconnection with the additional features to be herein described, thus making it necessary in a great number of cases for the automobile owner to purchase only a number of attachments for converting his foot pump unto a power driven pump.

lilith the foregoing general objects in view,

the invention resides in the novel features of construction and 'unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supple-l mented by the acconipanying drawings which form a part` of this specication and in which:

Figure 1 is a side elevation of a portion of an automobile and one forni of the inventionapplied thereto; l Fig. 2 is a perspective vieiv. of the pump and its operating' a attaching' means;

Fig. 11 is a vertical transverse section on the plane of the line 11-11 of Fig. 10;

. Fig. 12 is a disconnected perspective view of the pivotal connection shown in Figs. and 11;

Fig. 13 is a vertical section on the plane of the line 13h-13 of Fig. 10 showin the connection between the crank pin and the Tfshaped head of the piston rods as illustrating` the different mounting of said pin upon the wheel; and

Fig. 14 is a detail perspective view showing the connection between the crank pin and head in a more clear manner than illustrated in Figs. 10 and 13.

1n the drawings above briefly described, the numerals 1 designate the parallel cylinders of a common form of foot pump, one end of said cylinders being rigidly secured to a transverse foot plate 2 vvhich extends lat-- erally from said cylinders as Shown at 3. The opposite ends of the cylinders 1 are provided With the usual projecting piston rods 14 having threaded terminals 15, collars or other suitable shoulders ltat the inner ends of said terminals, and nuts 17 at the outer ends thereof. The handle shown in dotted lines in the drawings is commonly clamped in place upon the rods 14 by the nuts 17 and collars 16, but in the present invention, this handle is removed and a 'lshaped extension member or block 18 is substituted therefor, the head of said block being positioned between the terminals and provided in its ends with grooves or the like 19 receiving said terminals, said head being rigidly clamped between the collars 16 and the nuts 17 will be clear from the several vleivs. The shank 20 of the block 18, which shank forms an extension arm extending from the piston rods i C, is formed with an opening 21 to receive a crank pin En l" ti, the crank 22de pro the spokes of a rear Wheel ofthe at an veccentric point. The outer end 'of the Y vided at its inner end `with any preferred I type of clamp 23 for securing 1t to one of automobile,

pin in question is provided with a `lateral projection 24 and the side of the pin opposite said projection is rounded off at its' end as shown at 25. These' features are adapted to permit the pin to passthrough the opening 21 of thearm 20 when. the two are located at a suitable angle such as seen in Fig. 5, and in order that thel proper oper-y ation shall take place, the inner end'of said .opening 2l mergesinto 4elliptical shape as seen at 26. By this construction', they pin 22 'and the arm or shank 20 may b e quickly and easily connected when x necessary f0r use. Similarly, they car. t

laterally projecting studs`27 may be pro.

videdfor preventing earcess'ive inward movementof the arm 2O upon the crank p in 22. Y

In theform 'of the invention shown in Figs. 10, 13 and 14, the opening 21 may he.y

circular throughout its length since pin 23, although being provided with lateral pins or the like 27 tollim-it the inward movement of the arm, is provided with a cotter pin- 24 for preventing or permitting removal of the arm. In the figures last referred to, rather?. than provide the pin 2 2 Wit-h a clamp 'suchl as 23, itis carried by acrank'a-rm 28 extending from a collar 29 which surrounds and is held in place by'one of the hub caps 30, This form of attaching means Will be used on some makes of machines whereas a clamp such as 23 Will be necessary for attaching the invention to machines of other makes.

In the form of the invention shown in l Figs. l to 9, a flat arm or bar 31 is secured to one of the running boards 32 and extends :laterally therefrom, the projecting end of said arm-being provided with a longitudinal 'slot 33 adapted to receive one of the proi jecting ends 3 of the foot plate 2, in'a rather loose manner, so that although the pump will be held against longitudinal shifting, it

will be permitted to oscillate as the rotating Wheel moves the crank pin 22 ou an arcuate path land Qperates the piston rod 4 to actuate the pump. pistons. I n Fig. 9, bolts 34 are shown for securing the bar 31 to the running board 32, said bar preferably having a forked inner end 35 which straddles the nut of-one of the bolts. This form of attachinfr means is preferable on some types of ma chines, but in most cases, I Will provide a C clamp 36y (Figs. 1, 2, 'l and. 8) fordet-achably securing arm 31 in place. This clamp is adapted to engage the edge of the running board as shown clearly in Figs. 2 and7, the upper horizontal arm of the clamp lying upon the upper surface of said board while through vvhich the inner end' of f :br ,31e tends tocoxrtact withflthe Alower side. ofi'the, t 'l runnmg board, v so. that. tightening 10ft-the,
